Illumination L10 ( serial #2013Z1445 ) Nichia 219A HCRI 4 mode - in best black.
Used some several times on the flight deck being powered up by a genuine Eneloop ‘pro’ XX AA from Japan.
I cleaned and re lubed the threads with nyogel & nano oil.
Spare O Ring, & split ring.
very well centred LED and no sign of thread wobble.
never dropped.
got very minor anodising spots where a split ring was tried on.
Its worked flawlessly.
a very good little AA light here for you with the sought after nichia pinky white 219 tint!.
Purchased on my travels direct from Craig at illumination supply in California.
